java数字转为人民币大写汉字输出

好的，为您提供一个Java代码示例，可以将数字转换为人民币大写汉字输出：

import java.math.BigDecimal;

public class NumberToChinese {
    private static final String[] CN_UPPER_NUMBER = {"零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖"};
    private static final String[] CN_UPPER_MONETARY_UNIT = {"分", "角", "元", "拾", "百", "千", "万", "亿", "元"};
    private static final BigDecimal MAX_VALUE = new BigDecimal("9999999999999.99");

    public static String number2CNMonetaryUnit(BigDecimal money) {
        if (money == null) {
            return "";
        }
        if (money.compareTo(MAX_VALUE) > 0) {
            return "";
        }

        StringBuilder sb = new StringBuilder();
        int index = 0;
        boolean isZero = true;
        int value;
        String s = money.movePointRight(2).setScale(0, 4).toString();
        if (s.length() > 1 && s.charAt(s.length() - 1) == '0') {
            s = s.substring(0, s.length() - 1);
        }
        int len = s.length();
        if (len > 15) {
            return "";
        }

        for (int i = len - 1; i >= 0; i--) {
            value = s.charAt(i) - '0';
            if (value < 0 || value > 9) {
                return "";
            }
            if (value != 0) {
                isZero = false;
                sb.insert(0, CN_UPPER_MONETARY_UNIT[index]);
                sb.insert(0, CN_UPPER_NUMBER[value]);
            } else {
                if (!isZero) {
                    sb.insert(0, CN_UPPER_NUMBER[value]);
                }
                if (index == 2 || index == 6) {
                    sb.insert(0, CN_UPPER_MONETARY_UNIT[index]);
                }
                isZero = true;
            }
            index++;
        }
        if (isZero) {
            sb.insert(0, "整");
        }
        return sb.toString();
    }
}

使用方法：

BigDecimal money = new BigDecimal("1234567.89");
String cnMoney = NumberToChinese.number2CNMonetaryUnit(money);
System.out.println(cnMoney); // 壹佰贰拾叁万肆仟伍佰陆拾柒元捌角玖分

请注意，该代码示例只能处理小于等于9999999999999.99的金额，超出范围会返回空字符串。
